 * Hi,
 * After adding a plugin, like wp e-commerce and later I also tried others, on a
   fresh development installation I get Errors I don’t have on my live server like:
 * Undefined property: WP_Query::$post in C:\wamp\www\wpecommerce\wp-content\plugins\
   wp-e-commerce\wpsc-includes\theme.functions.php on line 1025.
 * When I look in this file WP indeed tries to do a call on $wp_query:
    ‘$product_id
   = $wp_query->post->ID;’
 * Does anybody knows why I get these errors on a fresh development environment 
   while I don’t have this problem on my live server?
 * Thanks, Marc
